DETAILED DESCRIPTION OF THE INVENTION

[0001]

2. Description of the Related Art A conventional metal case used as an outer box of various electric devices such as an audio / video device, a personal computer, and a printer includes a plurality of metal plates, for example, a double-sided plate and a top plate. After bending, such as press forming into a connected gutter shape, each metal plate is assembled in a box shape, and the joints between them are generally screwed and connected. there were. Then, these metal cases are assembled in a box at a case manufacturing plant, and then transported to an equipment assembling plant.

[0002]

However, if the transportation is performed in a bulky empty box, the assembly factory can save the labor of assembly, but from the viewpoint of transportation cost, the sea is particularly difficult. When transporting over long distances, etc.
It is extremely uneconomical.

In addition, an expensive press machine and a die for pressing a metal plate are required. Of course, the working environment is inferior, such as noise and danger involved in the press working. Therefore, it is desirable to simplify such workings as much as possible.

[0004] Further, from another point of view, when stacking quite heavy electrical equipment, it is difficult to say that a conventional case in which metal plates are assembled by screwing together is sufficient in load resistance. Further, the conventional one requires extra labor and cost for mounting the legs for ventilation and the like.

Therefore, the main object of the present invention is to store and store
During transportation, each component is disassembled and put together in a compact form, and when used, it is assembled very easily and quickly, and at the same time, it provides an assembly type case for electrical equipment that can significantly reduce the manufacturing cost. To be. And
An additional object of the present invention is to provide a load-bearing device that is superior to conventional ones, can withstand heavy stacking, can withstand stacking, and has leg portions for ventilation and the like. It is necessary to save the trouble of mounting.

[0006]

In order to achieve the above-mentioned object, an assembling type case for electric equipment according to the present invention is provided at four corners of a rectangular parallelepiped case, the corners being composed of metal columnar blocks. Each side plate 2 constituting the peripheral wall of the case is provided on a pillar 1.
Of the case are fitted into the recessed steps 6 and 7 on the bottom and top surfaces of the corner post 1 so that the four corners of the bottom plate 3 and the top plate 4 of the case are fitted respectively. The fitting state is fixed by an assembling screw 10 screwed into the corner post 1 through the four corners. Then, an insertion groove 11 for inserting the four corner portions of the bottom plate 3 or the top plate 4 may be provided on the side surface of the corner post 1.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows an assembled case A of this embodiment as an outer box of amplifiers.
1 was shown.

This assembling case A1 made of a metal such as aluminum is provided with corner pillars 1 arranged at four corners of the case, and four side plates 2 constituting a peripheral wall of the case, respectively.
The bottom plate 3 and the top plate 4 serving as the bottom and top surfaces of the case are the main constituent members.

The corner post 1 of this embodiment is formed in a prismatic shape as shown in FIGS. 2 and 3, and a pair of adjacent side surfaces is provided at each end of four side plates 2 at each end. Are provided as locking means for locking the side plate 2 to the corner post 1. Also, on the bottom and top surfaces of each corner post 1,
Square steps 6 and 7 for fitting four corners of the bottom plate 3 and the top plate 4 are provided in a concave shape.

The depths of the recesses at the step portions 6 and 7 are larger than the thicknesses of the bottom plate 3 and the top plate 4 by a predetermined dimension. A screw hole 8 is provided substantially at the center of each of the step portions 6 and 7. On the other hand, screw holes 9 are provided at each of the four corners of the bottom plate 3 and the top plate 4 at positions opposite to the screw holes 8. Each screw hole 8 has an assembly screw 1 inserted through each screw hole 9.
0 is screwed in.

Next, an example of an assembling procedure of the assembling case A1 will be described with reference to FIG. First,
The four corner posts 1 are placed on an assembling worktable (not shown) in such a manner as to be applied to the four corners of the bottom plate 3. Since the shape of the corner post 1 is symmetrical in the vertical direction, there is no distinction between the upper and lower sides.

Next, the four corners of the bottom plate 3 are fitted into the step portions 6 on the upper surface of each corner post 1 (the lower surface in the assembled state of the case). Then, when the assembling screws 10 inserted into the screw holes 9 of the bottom plate 3 are screwed into the screw holes 8 of the corner post 1, respectively,
The work of mounting the corner posts 1 downward at the four corners of the bottom plate 3 can be completed extremely simply and quickly.

Next, if the bottom plate 3 is turned upside down, although not shown, corner posts 1 are set up at four corners of the bottom plate 3. Therefore, as can be understood from FIG. 3, the both ends of each side plate 2 are inserted into these grooves so as to straddle between the respective engaging grooves 5 and 5 of each pair of corner pillars 1 facing each other. If
Each of the four side plates 2 is assembled between the four corner posts 1.

Therefore, finally, the four corners of the top plate 4 are fixed to the step portions 7 on the top surface side of each corner post 1 by the assembling screws 10 similarly to the bottom plate 3 so as to fit the four plates. The assembled state of the side plate 2 is also fixed at the same time, and the
Can be assembled very easily and quickly, and yet firmly. The procedure for assembling the case is not limited to the above.

In this assembled state, the bottom plate 3 is
Is lifted by a predetermined dimension from the bottom surface of the. Therefore, the lower end of the corner post 1 also serves as a ventilation leg of the assembling case A1.

The top plate 4 is provided at a position lower than the top surface of the corner post 1 by a predetermined dimension. Therefore, the assembled case A1
In the case of stacking heavy amplifiers, etc., externally mounted, the weight will be supported only by the four corner pillars 1 that are necessary and have sufficient load-bearing capacity. It is not necessary to apply a load to the side plate 2 and the top plate 4 made of steel.

Next, FIG. 4 shows an assembly type case A2 according to a second embodiment of the present invention. The difference from the assembly type case A1 of the first embodiment is that the bottom plate 3
At the four corners.

As shown in FIG. 4, the width of the insertion groove 11 is such that it does not reach the engaging groove 5 for engaging the side plate 2. In order to cope with this, L-shaped cutouts are provided at the four corners of the bottom plate 3 as indicated by the symbol a and the imaginary line.

In each of the above embodiments, the corner post 1 has a prismatic shape. However, the design may be changed as appropriate, for example, by making the corners of the post round.

[0020]

As is apparent from the above description, the assembled case for electric equipment according to the present invention has excellent practical effects as listed below. (A) During storage and transportation, it can be reduced to an extremely compact form divided into individual components before assembly. (B) Therefore, storage and transportation costs can be significantly reduced as compared with storage and transportation in a state where a box-shaped case is assembled as in the related art. (C) The assembly of the case can be performed extremely simply and quickly by simple locking and fixing means attached to the four corner posts. (D) By inserting the four corners of the bottom plate or the top plate into the insertion grooves of the corner posts, an extremely sturdy case is assembled. Needless to say, the number of screwed portions can be reduced. (E) The lower end of the corner post also serves as a leg of the case. (F) The manufacturing cost can be remarkably reduced because the pressing process of the metal plate as the material can be simplified. (G) When stacking cases housing heavy equipment, the load is reliably received by the corner pillars having sufficient load resistance.
